Kedu ihe njirimara akụrụngwa maka karama reagent plastik?
Karama reagent rọba bụ ụdị nkwakọ ngwaahịa a na-ejikarị maka reagents dị iche iche.Ọ nwere njirimara nke nnabata dị mma, nke na-adịghị egbu egbu, ịdị arọ dị arọ, na adịghị emebi emebi.Akụrụngwa ya na-abụkarị polypropylene.Kedu ihe njirimara nke akụrụngwa a?
Enwere iri puku kwuru iri puku ụdị kemịkalụ reagents, yabụ enwere ụdị karama reagent rọba dị iche iche.The size nke arụnyere karama ọnụ na-ekewa n'ime mbara ọnụ karama na mkpa ọnụ karama, na dị ka agba, ọ na-ekewa n'ime agba aja aja karama na ndị nkịtị karama.Polypropylene, dị ka isi ihe nhazi ya, nwere njirimara ndị a:
1. Njupụta dị ntakịrị, naanị 0.89-0.91, nke bụ otu n'ime plastik dị ọkụ.
2. Ọmarịcha n'ibu ọrụ, ma e wezụga mmetụta iguzogide, ndị ọzọ n'ibu ọrụ dị mma karịa polyethylene, na-akpụ mmepụta nhazi àgwà dị mma.
